Possible? Certainly. Almost anything is possible.
Probable? No. Jailbreaking is easy to distribute as it does not require you modifying the device's hardware. A hardware mod will never become popular because it is not a one click process. Anyone with the skills to hack an iPod in that way would probably just buy an iPhone.
